a. After the door ha's been properlyfseated under the action of the conpressor cams the locking of thedooris accomplished by forcing a series{of bolts llthrough thesockjets of the'loolt ring 15 against a lockingring 13.

Referringnow more particularly to, Figs. land 2 to6, inclusive, .whichdisclose the operating means formoving the bolts, a 'singlehand wheel32-has been provided forthe purpose of performing the various functions"mentioned. "The handwheel is secured to a shaft 33 rotatably andslidablysupported in the housing secured to, the front of, the'door 1. r Theinner end ofthe' shaft has a bearing 7 40 which is adapted to rotate, aswell as slide longitudinally, in a bearing socket-Q41 of the couplingsleeve 42.

Therefore,the line "repre sents a projected line or surface of strength,

said line being equal";to'substantially the' length of thebaseofthe"trianglefrepresenfluing a section of this bolt.
